What DNS Changes Are Required To Start Using Exchange 2013 Hosting With EcoCloud360?

Migration > DNS Setup
This article describes how you can start using Exchange Hosting with EcoCloud360.
Configure DNS
In order to start receiving mail to your own domain name, three DNS changes should be made:
  • MX record
  • Autodiscover record
  • SRV record
  • SPF record (optional)
Note: Due to the distributed nature of DNS, any changes made to DNS information may take from several hours up to several days to propagate accross the Internet.
MX record
The DNS MX record points to the server that accepts messages for your domain name. Multiple MX records pointing to different mail servers may exist for one domain name. In cases when multiple MX records are created, each MX record usually has a priority represented by a number. The lower the number is, the higher the priority of the MX record. You may want to leave your existing MX record in place. This is possible, but you will continue to receive messages on an external server (the server your MX record points to). In this case, forwarders should be configured from the external server to the EcoCloud360 server so that users start receiving messages in Exchange mailboxes.
Read the Knowledge Base article on What is an MX record? What is the correct syntax of MX records? What is priority? for more information.
To setup MX records please check following:
Priority: 10
Host: @
Points to: mx.spamexperts.com
Priority: 20
Host: @
Points to: fallbackmx.spamexperts.eu
Priority: 30
Host: @
Points to: lastmx.spamexperts.net
Autodiscover record
An Autodiscover record is required for automatic configuration of your mail client. It is also required for some important Exchange server services that will be unavailable if the Autodiscover record is missing. Although basic Exchange functionality (like sending and receiving messages) will work even if the Autodiscover record is missing, we strongly recommend that you create the record to avoid any issues.
Read the Knowledge Base article on What is an Autodiscover record and why do I need one? for more information.
To setup Autodiscover CNAME record please check following:
Record Type: CNAME
Host: autodiscover
Points to: autodiscover.sampledomain.com (Replace sampledomain.com with your own domain)
TTL: 1 Hour
SRV record
Depending on your DNS solution, you may be unable to implement SRV records. Contact your DNS hosting provider or your DNS administrator for guidance.
Please review DNS Service Location (SRV) records article by Microsoft for more details.
To setup SRV record please check following:
Record type: SRV
Name: @
Target: outlook.ecomail360.com
Protocol: _tcp
Service: _autodiscover
Priority: 0
Weight: 0
Port: 443
TTL: 10800 seconds
SPF record (optional)
An SPF record is an antispam measure. It defines the servers from which users send messages. All other servers (not mentioned in the SPF record) sending messages from user@yourdomain.com are considered to be servers used by spammers. Utilization of an SPF record can reduce the number of spoofed messages coming to your users' Inboxes by increasing the spam score (unless the domain has been white listed in the individuals’ mailboxes or account-wide within SpamStopper).
Read the Knowledge Base article on What is an SPF record? What do I need to do about it? for more information.
We recommend that you use Sender ID Framework SPF Record Wizard to create SPF record for your domain.
Following image demonstrates how SPF record is created at Godaddy (one of the largest domain name providers)
Record Type: SPF
Host: @
TXT Value: v=spf1 mx mx:edge.ecomail360.com ip4: ip4: ~all
Important: If you are using any other mail servers to send out emails, then you should also specify those servers' hostnames or ip addresses at SPF record.
Note: We strongly recommend creating an SPF record to protect yourself from spoofing. Make EcoCloud360 responsible only for email for your domain If you do not want EcoCloud360 to host your domain name, but you do want us to be responsible for all of the email on your domain, then you need to add/change your Mail Exchanger (MX) record on your current Name Servers to point to Exchange. You should set the EcoCloud360 Exchange server to have the highest priority (lowest number) when adding/changing the MX record.
